add no_std support (#42)

Browse Source 
* Metadata supporting scale-info can be decoded and serialized in no_std (#2)

* Metadata supporting scale-info can be decoded and serialized in no_std (feature flag scale_info)

* Changes from review: rename feature flag into full_derive

* Changes from review: std implies full-derive

* Changes from review: optimization

Co-authored-by: echevrier <edith.chevrier@scs.ch>

* split full_derive into decode and sered_codec features.

(drop new Debug impls)

* cargo fmt

* rename serde_codec to serde_full

* Prior to v14 everything was Debug.

Are there any downsides? Unused debug impls will just get optimised away won't they?

* rust fmt

* Debug for the masses. Make it work for no_std

* check all combos of features

(if this plays well with ci then we should double up,
doing the same again but target wasm32)

* all wasm feature combos
